Deng without the actual use of consideration air purifier.Since actual life is depending on relevant to above-mentioned actual use a variety of
Factor, therefore generate the problem that, most of users can replace or repair too early its pollution when following manufacturer's recommendation
Object removes structure so as to cause unnecessary cost or too late, it means that even if pollutant removal structure is being no longer able to
By pollutant grade drops as low as still being used when safety value.
